Fluid Dispensing System

摘要

Fluid dispensing system comprising a system of interconnected micro chambers (13) communicating with at least a fluid inlet (22) and with at least a suction port (26). Each micro chamber (13) has an output communicating with a needle (15) and has at least one side defined by a deformable membrane (34) subjected to a variable pressure so that a decrease of the pressure with respect to the pressure present at fluid inlet (22) is transferred to the system of micro chambers (13) through the suction port (26) thereby establishing a suction of fluid from the inlet (22) towards the chambers (13) that are filled. An increase of the pressure, causing the deflection of the membrane (34) towards the inner side of each micro chamber, will close each dispensing unit and provoke the ejection of the fluid contained in each chamber (13) of the dispensing unit content through the outlets.
